| fatslob-:O said: Don't just believe that the Tegra K1 can consistently pull off 33 Gflops/watt consistently as it often caps out at around 25 Gflops/watt cause of the fact that it throttles a lot. BTW don't expect much gains from going to a smaller process node as leakage issues become more apparrent so reducing power consumption at smaller process nodes will get harder and harder. Architectures also don't play a big role to performance gains in comparison to chip scaling so that's pretty much a moot point you've got on your hands. Just note that the IPad mini is using the same processors as the iPhones but instead of being clocked at 800 Mhz it's clocked at 1 Ghz so that's actually a small increase in power consumption compared to the iPhones. 5 watts are meant for noticebly bigger tablets. |
Architectures can play a major role in performace gains. I think 3-4 watts would be fine for a iPad mini sized Nintendo handheld though, isn't the Ps Vita around 3? Can't leakage issues be mitigated to some extent as well? I would think that as they mature that would be the case.
